What to disassemble to change thermostat


You will need to remove your air cleaner and duct assembly. You will then see the thermostat housing sandwiched between the back of the intake manifold and the exhaust crossover pipe. The service manual says to remove the exhaust crossover pipe, but trust me, you do not want to attempt this unless you have access to a torch to heat the nuts that hold the thing to the exhaust manifolds. If you break a stud, then you are going to be removing an exhaust manifold for broken stud removal. If you take the 8mm screws out of the heat shield on the exhaust crossover pipe, you can wiggle the heat shield out. This will provide enough room to get the lower thermostat housing bolt out. It is a pain to do it this way, but it works and will prevent broken exhaust pipe studs. Sometimes the little 8mm bolts will also break, but since they only hold the heat shield, it is of no great consequence.

Then all you have to do is remove the two bolts that hold the thermostat housing to the manifold. The thermostat is directly under it.
Then the only other real "trick" is getting the thermostat and O-ring to stay in the correct position while you put the thermostat bolts back in. A trick that I use is a small wooden wedge. I put the thermostat housing into place over the thermostat and O-ring, then place mt wedge between the thermostat housing and the crossover pipe to hold the thermostat housing in place while I start the bolts. Otherwise, the thermostat tends to slide out the bottom while you are trying to get the bolts started.

Let me know how it goes...

Heat core


More often than not the problem is a thermostat that is stuck open, causing heater output to take a very long time to heat up. Replacing the thermostat is as follows:
Disconnect the negative battery cable (if you have an anti-theft radio, make sure you have the code).
Drain the cooling system (petcock bottom of radiator)
Follow the top radiator hose back to where it connects to the engine.
The part with the two bolts in it that the hose connects to is the thermostat housing.
You may have to remove the hose in order to remove the housing.
When you have removed the housing, note the position of the thermostat before you remove it.
When installing, use new gasket, etc.
(you might be able to get away with not removing the radiator hose, but it is recommended)
Be prepared for a bit of spillage when you remove the housing.
Hope this helps you.

Have heating problem thermostat replaced


Thermostat replacement on 3.4 liter, Not the thermostat housing is between the Throttle body and exhaust crossover. If you have small haves and the right tools you can remove the two botls without removing the crossover and throttle body. The bottom bolt to the thermostat does not have to come all the way out, there is a cut out on the housing so you can slid it out. Good luck and take your time.

  1. Remove the air cleaner and duct assembly.
  2. Drain the coolant until the coolant level is below the thermostat.
  3. Remove the crossover exhaust pipe.
  4. Remove the radiator hose from the thermostat housing.
  5. Remove the thermostat housing bolts and clean any sealer from the bolt threads.
  6. Remove the thermostat housing and gasket.
  7. Remove the thermostat.
  8. Install the thermostat.
  9. Install the thermostat housing bolts and tighten them to 18 ft. lbs. (25 Nm).
  10. Install the radiator hose to the thermostat housing.
  11. Install the crossover exhaust pipe.
  12. Install the air cleaner and duct assembly.
  13. Good luck...
  14. Fill the cooling system.

Need to replace a Thermostat on a 2001 PT Cruiser. Have the new Thermostat need insturctions on how to do the replacement.


Most thermostats are located in the upper radiator hose housing mounted to engine block. Make sure engine is cold put a catch pan under your car to catch any antifreeze that comes out. Remove the two bolts holding the housing on the engine and remove thermostat and gasket. Clean engine block where gasket goes very good and also the housing, have to remove all gasket material so when installing new one it will seal and wont cause a leak. Make sure when you put the thermostat back in it goes in spring side down towards engine. Replace housing and bolts. replace lost coolant with a 50/50 mixture in your recovery tank. Start engine let heat to temp and check for leaks.
